Proper code for what?? First, no one is going to write your code for you. Second, what EXACTLY do you mean by "up and down record"?? Are you talking about moving record in the datatable you bound the grid to??

Sorry in advance. I'm not clear on what you are trying to do. So I made a genaric search for the datagrid, and may not be what you are looking for.

Sample (this will search (loop) all cells in the datagrid and return the first match):

private void TextBox_KeyDown(object sender, KeyEventArgs e) {
     if (sender == textBox1) { //TextBox
          //Search for... on Enter key, 
          //this can be any key allowed by the textbox
          if (e.KeyCode == Keys.Enter) {

               //check for no search data
               if (textBox1.Text != string.Empty || textBox1.Text != "") {
                    //get search for data
                    DataGridCell cell = SearchRecords(textBox1.Text); 

                    //check for valid cell, Not (-1,-1)
                    if(cell.ColumnNumber !=-1 && cell.RowNumber!= -1)
                         FocusOnEntry(cell);
               }
          }
     }
}

private DataGridCell SearchRecords(object data) {
     //Searches All Entries & Returns first matching

     //Get Counts for validation
     int c = dataGridView1.Columns.Count;
     int r = dataGridView1.Rows.Count;
 
     if (c != 0 && r != 0) { //Check if has Columns & Rows
          //Search Columns Left > Right & Rows Top to Bottom
          for (int col = 0; col < c; col++) {
               for (int row = 0; row < r; row++) {
                    //Check Values for Match
                    DataGridViewCell cell = dataGridView1[col, row];
                    if (cell.Value != null && cell.Value.ToString() == data.ToString())
                         return new DataGridCell(row, col); //found
               }
          }
     }
     return new DataGridCell(-1, -1); //not found
}

private void FocusOnEntry(DataGridCell index) {
     //Select the Row & Focus
     dataGridView1.Rows[index.RowNumber].Selected = true;
     dataGridView1.Focus();
}

Let me know if this is what you are looking for.

Yes, but you need to handle the keydown or keypress event for the textbox.

Example: keydown event for the textbox.

private void TextBox_KeyDown(object sender, KeyEventArgs e) {
     if (sender == textBox1) { //TextBox
          //Adjust Indexes
          if (e.KeyCode == Keys.Down) {
               int c = dataGridView1.CurrentCell.ColumnIndex;
               int r = dataGridView1.CurrentCell.RowIndex;
               if (r < dataGridView1.Rows.Count-1) //check for index out of range
                    dataGridView1.CurrentCell = dataGridView1[c, r + 1];
          }
          if (e.KeyCode == Keys.Up) {
               int c = dataGridView1.CurrentCell.ColumnIndex;
               int r = dataGridView1.CurrentCell.RowIndex;
               if(r > 0) //check for index out of range
                    dataGridView1.CurrentCell = dataGridView1[c, r - 1];
          }
     }
}
